Abstract

Concrete is a potential construction, waste package and backfill, material for disposal- of low and intermediate level nuclear wastes. Sorption of 90Sr, 137Cs, 129I and 14C in concrete and in sand ballast used as aggrepte of concrete was determined by measurement of 85Sr, 134Cs, 125I and 14C isotopes using the batch method. Natural ground waters from planned disposal sites were used, and for aggregate also ground water equilibrated with concrete. The sorption order of the different samples for cesium and strontium was Kd (aggregate + ground water) > Kd (concrete + ground water)> Kd (aggregace + ground water equilibrated with concrete). For iodine and carbon the order was Kd (concrete + ground water)> Kd (aggregate + ground water equilibrated with concrete)> K (aggregate + ground water). In the case of cesium the K -values were > 100 ml/g for all samples. The Kd -values of strontium were <25 ml/g and of iodine< 10 ml./g. The Kd -values of carbon were about 2 and 100 and 2 000 ml/g for aggregates with around water, aggregates with ground water equilibrated with concrete and concrete with ground water, respectively.
